DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for removing a hydraulic inorganic molded article.

[0002]

2. Description of the Related Art Conventionally, a so-called hydraulic inorganic molded article molding apparatus for supplying a hydraulic inorganic material to a cavity formed between a lower mold and an upper mold of a molding die and obtaining a molded article by vacuum dehydration molding. In this method, a take-out device for taking out the molded product from the lower mold after the mold is opened by vacuum suction is used. An example of such an apparatus for taking out a hydraulic inorganic molded article is disclosed in
-74789.

As shown in FIG. 6 and a top view of FIG.
A vacuum suction plate 300 provided with a vacuum suction hole 200 in communication with the cavity is provided in an integrated structure with the fixture 400 so as to suck the molded product 100. The attachment section 500 on the upper surface of the attachment 400 is attached to a transfer device (not shown), and is moved to the next step.

[0004]

However, in the conventional take-out device as shown in FIG. 6, the vacuum suction plate 300 is provided integrally with the fixture 400 in order to vacuum-suck the molded article 100. During a long use period, when the molded product is adsorbed, solids such as cement of the molded product are sucked and accumulated in the vacuum suction plate 300 from the vacuum suction hole 200, and the vacuum suction hole 200 is clogged. Becomes
There is a problem that poor adsorption of the molded product occurs.

In a vacuum suction tool used in a large-sized molding apparatus such as a multi-cavity molding (three-cavity molding in the case of the molding apparatus shown in FIG. 6), a vacuum suction chamber or a clogged vacuum suction hole is cleaned. Even so, there is a problem that maintenance is difficult because the vacuum suction chamber is integrated with the vacuum suction tool.

The present invention has been made in view of the above-mentioned problems, and an object of the present invention is to solve these problems and to clean the vacuum suction chamber and the vacuum suction holes. An object of the present invention is to provide an apparatus for taking out a hydraulic inorganic molded article which can be easily and easily performed, does not cause poor adsorption of the molded article, and has excellent maintainability.

[0007]

According to the present invention, there is provided an apparatus for taking out a hydraulic inorganic molded article, wherein the hydraulic inorganic molded article formed by a cavity formed by an upper mold and a lower mold is opened by vacuum suction. A device for removing a hydraulic inorganic molded product to be removed from a lower mold later, wherein the removal device is detachable on an upper surface of the vacuum suction disk provided with a vacuum suction hole for vacuum-sucking the molded product. And a transfer device provided with a vacuum suction chamber on the upper surface.

[0008]

In the apparatus for removing a hydraulic inorganic molded article according to the present invention, the removal apparatus comprises a vacuum suction disk provided with a vacuum suction hole for vacuum-sucking the molded article, and is detachably mounted on the upper surface of the vacuum suction disk. And a transfer device provided with a vacuum suction chamber on the upper surface. In a state where the vacuum suction plate is detached from the transfer device, the inside of the vacuum suction plate is entirely opened, so that the vacuum suction plate is accumulated inside. The solid portion such as cement can be easily and easily cleaned, and the vacuum suction hole can be easily cleaned from inside and outside, so that the maintenance property can be excellent. Furthermore, since the vacuum suction holes are not clogged and poor suction of molded products does not occur, productivity can be improved.

FIG. 1 is a sectional view showing an example of an apparatus for taking out a hydraulic inorganic molded article. As shown in FIG. 2, the take-out apparatus 10 for hydraulically molded inorganic products according to the present embodiment shown in FIG. 1 is formed by a three-cavity 3 formed by an upper mold 1 and a lower mold 2 of the molding apparatus. Hydraulic inorganic molded article 3
This is a device for taking out a hydraulic inorganic molded product from the lower mold 3 after mold opening by vacuum suction.

The unloading device 10 is a vacuum suction disk 1 provided with a large number of vacuum suction holes 11a for vacuum suction of a molded product 3A.
1 and a transfer device 12 detachably attached to the upper surface of the vacuum suction disk 11 and provided with a vacuum suction chamber 12a having an opening 12b on the upper surface.

The transfer device 12 has a packing 13 surrounding the packing 13 for sealing the inside, and the vacuum suction plate 1
1 has a structure that can be attached by using a clamping metal 14.

The molded product 3A (shown in FIG. 2) in the lower mold 2 after the molding is completed and the upper mold 1 is removed by opening the mold,
Due to the vacuum suction action of the vacuum suction chamber 12a evacuated by the unloading device 10, the suction is performed by the vacuum suction holes 11a of the vacuum suction disk 11 that is communicated with the vacuum suction chamber 12a, and is once raised above the lower mold 2. It is transported up and down, transported to the next process position, placed on a receiving mold 4 as shown in FIG. 3, and cured and cured.

When the transfer device 12 above the take-out device 10 of the present embodiment is removed, as shown in FIGS. 4 and 5, the upper surface (inside) of the vacuum suction plate 11 is completely opened. State.

Accordingly, it is possible to easily and easily clean solid parts such as cement accumulated in the vacuum suction disk 11 in a short time, and it is also possible to easily and easily clean the vacuum suction holes 11a from inside and outside. Thus, excellent maintainability can be obtained. Further, since the vacuum suction hole 11a is not clogged, poor suction of a molded product does not occur, and productivity can be improved.

[0015]

According to the apparatus for removing hydraulic inorganic molded articles of the present invention, the removal apparatus is provided with a vacuum suction disc provided with a vacuum suction hole for vacuum-sucking the molded article, and is detachably mounted on the upper surface of the vacuum suction disc. , And a transfer device provided with a vacuum suction chamber on the upper surface, so that when the vacuum suction plate is removed from the transfer device, the inside of the vacuum suction plate is fully opened. The solid portion such as the accumulated cement can be easily and easily cleaned, and the vacuum suction hole can be easily cleaned from inside and outside, so that the maintenance property can be excellent. Furthermore, since the vacuum suction holes are not clogged and poor suction of molded products does not occur, productivity can be improved. Therefore, it is suitably used as a device for taking out a hydraulic inorganic molded article.
